“…Red shifts toward a high binding energy were far from the pure TiO 2 (452.92 and 464.89 eV). This binding energy shifts could be due to a change in the chemical state or electronic interaction between the PANI surface and the TiO 2 nanoparticles [61]. From Figures 13b and 14b, three peaks located at 284.31, 284.9 and 286.94 eV were observed and can be attributed to C-C, C-O, and C=O, respectively.…”

Polyaniline (PANI) thin films incorporated with TiO2 or ZnO nanoparticles were synthesized via an electrochemical polymerization technique. Cyclic voltammetry (CV) was used to synthesize PANI from a strongly acidic medium (0.5 M H2SO4). The effects of different deposition cycles on the morphology, thickness, color, and properties of electrodeposited PANI thin films nanocomposites were investigated. Furthermore, the effects of the nanoparticles concentration on the morphology and water contact angle (CA) of the produced coating were investigated. Field-emission scanning electron microscopy (FE-SEM) and high-resolution transmission electron microscopy (HR-TEM) were used to investigate the morphological structure. X-ray photoelectron spectroscopy (XPS) was used to study the surface composition of the formed film. The results reveal that the CA of the prepared coating reached 146°. A granular morphology of PANI with a moderate concentration of nanoparticles was obtained. In addition, XPS analysis confirmed the incorporation of the oxide nanoparticles in the matrix.

“…The corrosion potential (E corr ) of the uncoated samples (-151.36 mV SCE ) shifted to the nobler direction after GO coating (-71.10 mV SCE ), and laser/ GO coating (-33.75 mV SCE ). This shift toward nobler direction can be due to the ionic transfer by laser/GO coating [46]. The uncoated Ti-Nb SMAs presented the highest corrosion current density (i corr ) compared with the coated alloy owing to the presence of effective barrier layer on the Ti-Nb alloy surface, hence preventing the interaction between the corrosive medium and the substrate [47].…”

“…This indicates that a high level of corrosion protection of the Ti-Nb SMAs substrate can be provided by laser/GO coating by increasing the adhesion between GO coating and the substrate through laser treatment of the surface. The presence of such a protective coating film decreases the penetration of the electrolyte to the surface of TiNb SMAs and creates a barrier for blocking the ionic transport in the substrate[46].…”

“…Additionally many modifications of Ni matrix like Ni-Zn [15], Ni-W [16], Ni-B [17], Ni-Co [18], Ni-Mo [19] were investigated. The codeposition of TiO 2 with graphene nanosheets (GNS) in Ni matrix was also successfully demonstrated [20]. As the substrate material mainly mild steel or cooper were used.…”

“…Most of the nc-TiO 2 / Ni coatings examined previously was deposited using classic Watts baths, e.g. [1,6,18,20]. The citric-sulfate bath, which was used for deposition nc-TiO 2 /Ni coatings in this study, is a good alternative to Watts bath.…”

The aim of this work was to obtain composite of nc-TiO 2 /Ni coatings on 316L steel and to characterize their corrosion resistance. In order to investigate the influence of the addition of TiO 2 nanoparticles, both pure Ni and composite nc-TiO 2 /Ni coatings were electrodeposited from nickel citrate baths. The microstructure of the coatings was examined by scanning and transmission electron microscopy. The nc-TiO 2 /Ni coatings were about 10 μm thick. Their microstructure consisted of TiO 2 nanoparticles uniformly distributed in nanocrystalline Ni matrix. The corrosion resistance of the coatings was measured using impedance spectroscopy and polarization curves techniques in Ringer's solution. It was determined that the addition of nano-TiO 2 particles improved corrosion resistance and reduced corrosion rate of the coated steel.
